    摘要: A high density multilayer printed circuit board comprising generally parallel signal layers, electric source layers, and ground layers, with insulating layers arranged between the signal layers and the electric source layers, between the electric source layers and the ground layers, and between the ground layers and the signal layers respectively. Conductor portions are formed in through holes which are opened in a direction transverse to the signal layers, electric source layers, and ground layers. The conductor portions are electrically connected to the signal layers and/or the electric source layers, and/or the ground layers, through the lands thereof, the connections of the lands being substantially equally distributed among the conductor portions.

    摘要: A multilayer printed wiring board having an air gap between neighboring printed wiring boards of the multilayer printed wiring board by inserting plated spacers to both end faces of through-hole pads which are provided to each printed wiring board so that each through-hole pad opposes to another through-hole pad on the neighboring printed wiring board. The spacers opposed to each other are joined together by solder, and each spacer has an end surface having a size being smaller than a size of the end surface of each through-hole pad to provide a drop part at the joint part of the spacers, so that melted solder stays at the drop part not flowing toward the board through the side surface of the through-hole pad when the printed wiring boards are integrated to the multilayer printed wiring board under pressure and high temperature.

    摘要: A connector comprising a plug member having pin-like male contacts and a jack member having female contacts, the jack member being coupled with the plug member by a plug-in connection. A skirt having a plurality of holes is arranged to hold the pin-like male contacts in position. The skirt is supported in the plug member by the locating groove-pin engagement. The locating groove-pin engagement is released by the jack member when the jack member is inserted into the plug member and reestablished by the jack member when the jack member is withdrawn from the plug member. The skirt also has an alignment pin which is received in a locating hole of the jack member when the jack member is inserted into the plug member. Therefore, it is possible to insert the jack member in the plug member without the pin-like male contacts being bent, as well as to easily withdraw the jack member from the plug member.
